TYPE HOLDER FOR PRINTING PRESSES.

Application fi1er1.Novemher 12, 1923. Serial No. 674,140.

To all whom it may concern:

Beit known that I, NELSON I-viis, a citizen of the United States, and ,a resident of Topeka, in the county of Shawnee andState oil .liansas, have invented certain new and useful Improvements in Type Holders for Printing Presses; and I do hereby declare that'the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in type holders for printing presses, and refers more specifically to anovel arl'ungenient and construction for detachably' fining a type form to .a printing press bed .insuch a way that the forms and blocks in which they are set can be readily removed from the bed and another like form and block substituted in its place whereby, after a number of type and other impression elements have been composed or set up in dillerent blocks in the composing room, they can bentaken to the press room and successively mounted on the printing press :bed so that a limited number 0t copies ,can be run from each term, whereupon the forms and their supporting blocks can be removed tram the bed and other terms substituted therefor,-.tor a like limited run, and so on until all of the dorms are run, and in a manner to keep the press in operation.

The V invention is especialy useitula printing establishment vwhere alarge number .o-lf similar orders come inter @printing a limited number of individual copies such, for instance, as letter sheet headings and envelope return cards. The individual orders are usually for a limited number of copiesor sheets. For instance, ,in stationery printing it is customary tor an individual to order a limitednumber of letter sheets and a smaller number or envelqpes,iwith the headingon the sheet ito'be .the same as lhe return card on the envelope. In an organized printing, establishment for (this work, orders come ,in rt'rom many dilterent customers for such limited quantities and wherein the dimensions o l. headingsand ,return cards are substantially uniform as to width and length.

I-lerctotore, so far as I :am aware, it has been the custom to gillieilt each order separately in thesensc of the make-ready tor the forms and locking them in the chase by the use ofknown furniture or quoins. A disadvantage of this practice is that after a given order has been printed it is necessary to disassemblet he chase elements and make ready another form and lock itin the same chase,-work which requires considerable time and necessitates consequent lengths of idle periods for the press.

In accordance with the present invention, it is ,proposed to provide the bed plate of the press with a single holder adaptable to readily and successively receive a number of type blocks in which the type for different orders are set up in theicomposing' room so that when said blocks coineto the press rooin they icau bereadily inserted into the holder until the required number of copies have been printed,' whereupon the blocks carrying the type forms last used in print ing can be quickly removed and block and type form for the next order quickly \inserted into its place, so that the succeeding orders represented by .thedifl'erent blocks and type forms carried thereby can be used for printing succesive orders with little or not time :lost in the stoppage .ort'the press.

In an order of usual size, it has been vthe experience that three or four'bloclrsican thus be ,used with one pres, ,that is to say, with the terms beingcomposed intone block while the other blocks are .in the press or the type thereliroin is being distributed.

In-printing letter headings and envelope return cards, it is practicable to use two presses, one for the letter heads and the other for the envelopes. and when rhis practice is followed block and its form, which has been used in the letter head press, can be remoyed to the envelope press, while a block and fornr representing another order can be substituted in the letter head press.

More than one of such type block holders may be employed on arsingle press bed where-a number of headings areto be run at the same timeonIone press, after which the stock is cut in a cutting machine to correspond with the number of headings run.

In the drawings illustrating two embodiments otthe invention:

Fig. l is a perspective view of a press bed showing the adaptation of my invention thereto,

Fig. 2 is a fragmentary section on the line 22 of Fig. 1.

Fig. 3 is a face View of a press bed showing the adaptation of two type holders thereto.

Fig. 4: is a perspective of one of the .ele-

ments of the holder.

Fig. 5 is an elevation on a reduced scale of the type holder adapted as a unitary chase.

The press bed 10, shown in Fig. 1, is part of the known Gordon type printing press,

, the number of blocks referred to which will serve a press, and the type of some of which can be composed and distributed, while the type of another block or blocks are run in the ress. The type may be individual types or s ugs and are spaced in the opening 13 in any preferred or known way and wedgelocked in said block. When the type are so locked, the blocks can be handled without danger of pieing the type.

The holder that is fixed to the bed 10 embodies as its principal characteristics an open way into which the blocks can be slid and supports or stops on which the blocks are supported or gauged when in the holder,

v the holder being so arranged that the finger and thumb of the press operator can be placed on the upper and lower sides of the block when setting it in the holder or re moving it therefrom.

A practical form of holder when used with an upright bed comprises two L-shaped parts 15, the longer legs 16 of which lie parallel to the plane of the bed, and the shorter legs 17 of which are directed toward but spaced from each other. The distance between the ends of the longer legs of the L-shaped parts is suiiicient to permit the block 12 to freely and snugly slide into the holder, but without causing the block to bind when the block is being set into or removed from the holder. The shorter legs 17 of the L-shaped pieces constitute the stop or support for the block, and the space 18 between the facing ends of said shorter legs affords room for the finger or thumb of an operator when placing the block into or removing it from the holder thus described. The arms 16 constitute the sides of a trough, of which the press bed is the bottom, to receive and hold the block. 7

No separately formed and applied device is required to lock the block in the holder, but in order to prevent the block tilting and holding it against the bed plate the proximate faces of the longer legs of the L-shaped pieces of the holder may be beveled, as shown at 19, to fit the correspondingly beveled ends 20 of the blocks.

The bed plate in Fig. 1 is provided with a single holder, while that shown in Figure 3 is equipped with two holders for printing two up jogs as, for instance, where the stock is printed double size and is afterwards cut to proper size by a cutting machine. In larger presses three or more of such holders could be used, depending on the size of sheet to be run. After running on such a large press, the blocks can be removed and run singly on another press for printing the envelopes. This is a feature of very considerable importance in respect of saving time.

Another feature of utility of the type block provided with the small rectangular opening, as shown, is that when the type are locked in the block, as by the wedge 20, there is so small an amount of material in the lock-up that the type is not forced or strained off its feet. Therefore, when the block and the type are placed in the press, the feet of the type set solidly against the bed, thereby giving agood, even impression when the stock is pressed against the type by the movement of the platten. It has been found that in looking up an ordinary type form in chases, such as have heretofore been used, the operator must be very careful in locking up the type so that it will not be forced off its feet owing to the amount of material in the chase. Under these conditions when the chase is set in the press the form does not rest solidly against the bed of the press and does not give a uniform impression. In the use of a chase, when changing from one form to another, the variation in squeeze must be compensated for by adjustment to the press.

In Figure 5 is shown a modification wherein the holder, comprising the L-shaped members 22, disposed in relation to each other as before described, are made an integral part of a chase 23 which will be supported on the type bed 10 in the usual manner of fixing and supporting a chase thereon. In this construction the L-shaped holders are made integral with connecting mem bers 24, 25 which are in turn made integral with the ends and bottornrespectively of the chase frame.

It is apparent that the invention herein disclosed overcomes many of the difliculties experienced in job press work, produces better printing, and reduces the overhead by keepingthe press in substantially constant operation. It is to be understood that the invention is capable of adaptation to other forms of presses than the vertical bed type without sacrificing the advantages and utility of the invention.

What I claim as new and desire to secure by Letters Patent is l. A type holder for printing presses adapted to be applied to the fiat face of a press bed and to receive and laterally sup port a type carrier or block which rests in contact with said bed, said holder being provided at one end with a free inlet and outlet for a carrier that is guided and held in position on said bed between lateral inwardly facing surfaces of the holder, and provided at its other end with a stop or support for said carrier.

2. A type holder for printing presses adapted to receive and support a type carrier or block, said holder being provided with a free inlet and outlet for the carrier that is guided and held in position between surfaces of the holder, said holder being formed at its side opposite said inlet and outlet with a finger opening to engage one side of the carrier.

3. A type holder for printing presses adapted to be attached to and in contact with the bed of a press, said holder comprising holding and guiding arms which flank the type supporting face of the bed, and between the free ends of which is formed an outlet and inlet for a type carrier, and at the opposite ends of which are formed a support for the carrier.

4. A type holder for printing presses adapted to be attached to and in contact with the bed of a press, said holder comprising holding and guiding arms to constitute the sides of a trough, of which the arms are the sides and the bed is the bottom, and between which arms, at one side of the holder, is formed an outlet and inlet for a type carrier, and formed at the other end of the holder with supports for the carrier, the proximate faces of said arms being under cut beveled to contact with corresponding bevels on the gauging ends of said carrier.

5. A type holder for a printing press having a substantially upright bed embracing guides which are free ended at their upper sides to permit a type carrier to pass between the guides and to be supported on the bed, said guides also beingformed at their lower ends with spaced carrier supports.

6. A holder for a type carrier having an opening in which the type form is composed, comprising two L-shaped members with their shorter ends spaced and constituting a support for the carrier, and with their longer ends spaced to provide an outlet and inlet for the type carrier.

7. A holder for a type carrier having an opening in which the type form is composed, comprising two L-shaped members with their shorter ends spaced and constituting a support for the carrier, and with their longer ends spaced to provide an out-- let and inlet for the type carrier, said holder members being adapted to be fastened to the face of the bed, and having guiding engagement with the type form carrier to hold said carrier against the bed.

In witness whereof I claim the foregoing as my invention, I hereunto append my signature this 5th day of November, 1923.

NELSON IVES.
